An apparatus for optical measurement is formed as a one-piece molding. The apparatus has a reaction vessel and pre-treatment vessels, at least part of the partitioning wall between the both serves as an optical waveguide body, and a light absorber vessel is formed adjacent the reaction vessel (24). Simplification of the process of manufacture thus is attained. With a light absorber accommodated in the light absorber vessel, (25), reaction components of excitation light and other noise light components that are propagated through the optical waveguide body can be sufficiently attenuated to improve the S/N ratio of the optical measurement.
An apparatus for use in an optical measurement assembly, said apparatus comprising a plurality of vessels (21 to 24, 51 to 55) formed together as a monolithic molding, at least one of said vessels being a reaction vessel (24), said reaction vessel (24) facing at least one other vessel along a facing side wall of said monolithic molding, the facing side wall of said reaction vessel also being an optical waveguide (1) in said apparatus.
An apparatus for use in an optical measurement assembly, said apparatus comprising a plurality of vessels formed together as a monolithic unit, at least one of said vessels being a reaction vessel, said reaction vessel facing at least one other vessel along a facing side wall of said monolithic unit, the facing side wall of said reaction vessel being an optical waveguide in said apparatus for optical measurement wherein said optical waveguide has a light incidence/emission prism provided at one end for introducing excitation light into it in order for the excitation light to be propagated while being totally reflected and also for emitting signal light containing optical measurement information, and a light absorber storing vessel being disposed such as to correspond to the other end of said optical waveguide.
An apparatus for use in an optical measurement assembly, said apparatus comprising a plurality of vessels formed together as a monolithic molding, at least one of said vessels being a reaction vessel, said reaction vessel facing at least one other vessel along a facing side wall of said monolithic molding, the facing side wall of said reaction vessel being an optical waveguide in said apparatus for optical measurement, wherein a side portion of said reaction vessel that extends substantially at right angles to said optical waveguide and that is positioned on an excitation light introduction side of said optical waveguide and/or on a side extending substantially parallel to said optical waveguide is coated with a black paint.
